Well I didn't like how the original behaved so I created my own in two simple scripts.
The east and the south version (I realise that the diffrence is small but there is one).
Just drop it into your custom directory restart the server and than simply add candleskulls or candleskulle.
The diffrence between original and mine is that mine will not change facing when lit or unlit.
Simple but effective
BTW the original burnout of 25 minutes has been edited out so if you still want that just delete // at the end of the scripts.
